About

This Phase II, open-label, three-arm randomized controlled trial (RCT) will investigate the effects of 12 weeks of aerobic exercise vs. 12 weeks of resistance exercise vs. usual care in men with metastatic castration resistant prostate cancer to determine the safety, feasibility, and tolerance of exercise; quality of life indicators, and a prognostic score.

Full description

This is a PI-initiated, randomized clinical trial of 12 weeks of aerobic exercise vs. 12 weeks of resistance exercise vs. usual care among 39 men with metastatic castration resistant prostate cancer. Eligible men will be randomized with equal probability to one of the three regimens. All patients will receive a packet of print material on diet, exercise, and psycho-social support appropriately geared for men with late stage disease at the end of the trial. The aerobic exercise arm (N=13) will receive a 3 day/week remotely-supervised exercise regimen that includes high-intensity interval training and continuous vigorous intensity aerobic exercise training. The resistance exercise arm (N=13) will receive a 3 day/week remotely-supervised resistance exercise regimen incorporating different volumes and loads. Men in the control arm (N=13) will be asked to continue their typical exercise practices for 12 weeks. Subjects will be asked to complete questionnaires, physical function and strength tests, body measurements, and collection of blood specimen at baseline and 12 weeks.

Enrollment: 28 patients

Sex: Male

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Histologically documented adenocarcinoma of the prostate with systemic bone or node metastatic disease despite castrate levels of testosterone (<50 ng/dL) due to orchiectomy or luteinising hormone-releasing hormone (LHRH) agonist. Castrate levels of testosterone must be maintained while on study. Men can be enrolled prior to starting abiraterone and/or enzalutamide OR already be receiving treatment with abiraterone and/or enzalutamide.

• On androgen deprivation therapy (ADT) with a Gonadotropin-releasing hormone (GnRH) agonist/antagonist or prior bilateral orchiectomy. All patients will be required to be on ADT throughout the study.

• ≥4 weeks since any major surgery and fully recovered

• Eastern Cooperative Oncology Group (ECOG) performance status 0-1

• Required Initial Laboratory Values:

  • Platelet count ≥ 100,000/microliter (uL)
  • Hepatic and renal dysfunction that would preclude participation in an exercise program, in the opinion of the treating physician
  • Serum testosterone ≤ 50 ng/dL

• Medical clearance to undergo steep ramp test and completion of steep ramp test

• Physician consent to participate in vigorous aerobic or resistance exercise training

• Age ≥18 years

Exclusion criteria

• Men with small cell neuroendocrine tumors or features of small cell disease
• Chemotherapy criteria: Metastatic castrate-resistant prostate cancer (CRPC) pre-chemo (metastatic castration-resistant adenocarcinoma prostate cancer, pre-CRPC chemotherapy), which is given for hormone-sensitive prostate cancer, is allowed. Metastatic CRPC post- chemo (metastatic castrate-resistant adenocarcinoma prostate cancer, post-CRPC chemotherapy) is allowed with the treating physician's (oncologist) discretion/approval.
• Poorly controlled hypertension
• Any contraindications to vigorous exercise, including, but not limited to: brain metastases, current congestive heart failure, serious or non-healing wound, and no serious cardiovascular events within 12 months
• Experiences shortness of breath, chest discomfort, or palpitations when performing activities of daily living (can participate with cardiologist clearance)
• Has difficulty climbing a flight of stairs due to physical impairment
• Has been recommended by a doctor to only medically supervised activity
• Has chest pain brought on by physical activity (can participate with cardiologist clearance)
• Has developed chest pain in the past month (can participate with cardiologist clearance)
• Serious or non-healing wound, ulcer, or bone fracture
• Spinal cord compromise or instrumentation due to metastatic disease. Radiation therapy for metastatic disease is allowed.
• Serious or non-healing wound, ulcer, or bone fracture.
• Spinal cord compromise or instrumentation due to metastatic disease. Radiation therapy for metastatic disease is allowed.
• Any peripheral neuropathy ≥grade 3
• Moderate-to-severe bone pain (i.e., National Cancer Institute's Common Terminology Criteria for Adverse Events grade 2-3 bone pain).
• Men participating in vigorous aerobic exercise for 75 minutes or more per week and/or resistance exercise three or more days per week
• Men who do not complete the baseline lifestyle and quality-of-life questionnaires

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

28 participants in 3 patient groups

Experimental: Arm 1 (Aerobic Exercise)

Experimental group

Description:

Arm 1 will engage in a periodized program consisting of 3 aerobic exercise sessions per week comprised of two high-intensity interval training workouts and 1 continuous vigorous intensity workout. A physical assessment, physical function and strengths tests, and questionnaires will be completed at baseline and 3 months.

Treatment:

Behavioral: Experimental: Arm 1 (Aerobic Exercise)

Experimental: Arm 2 (Resist. Exercise)

Experimental group

Description:

Arm 2 will engage in a periodized program consisting of 3 resistance exercise sessions per week comprised of various loads and volumes. A physical assessment, physical function and strengths tests, and questionnaires will be completed at baseline and 3 months.

Treatment:

Behavioral: Experimental: Arm 2 (Resist. Exercise)

No Intervention: Arm 3 (Control)

No Intervention group

Description:

Arm 3 will follow their usual exercise and lifestyle routine. A physical assessment, physical function and strengths tests, and questionnaires will be completed at baseline and 3 months.
